Cam switch, 0-1, 3-pole, for busbar, black lockable knob SK125-4.4284\BS07

Cam switch for busbar – reliable disconnection in the installation

This three-pole cam switch SK125-4.4284\BS07 is a solid solution for safely disconnecting circuits in electrical installations. Designed for mounting on a busbar, it provides convenient and reliable operation, and its construction guarantees high reliability. The key-lockable knob increases safety, preventing accidental disconnection of the circuit.

Construction and application

The cam switch SK125 BS is intended for use in switchgear cabinets, control panels and other installations requiring frequent disconnection of circuits. Its design allows for quick and easy switching, which is particularly important during maintenance or emergency work. The ability to mount up to 7 segments allows the switch to be adapted to the specific needs of the installation. A continuous rated current of 125A makes it suitable for circuits with high loads.

Key features and benefits

• Durability and reliability: Rated short-circuit current of 2.5 kA and high resistance to environmental conditions (operating temperature from -40°C to +70°C) ensure long-lasting and trouble-free operation.
• Safety: Black key-lockable knob minimizes the risk of accidental disconnection of the circuit, which is particularly important in industrial and commercial applications.
• Versatility: The ability to connect wires with 8 mm eyelet terminals and mount on a standard TS35 busbar facilitates integration with existing installations.
• High resistance: Protection class IP65 guarantees protection against dust and moisture, allowing the switch to be used in harsh environmental conditions.
• Wide voltage range: Rated insulation voltage of 690 V enables use in various energy applications.
• Flexibility: The ability to connect from 1 to 7 segments allows you to adapt the switch to specific installation needs.
• Easy mounting: Mounting to the panel using M8 screws with a tightening torque of 12 Nm ensures a stable and secure connection.

The rated insulation voltage (Ue) is 690 V, and the continuous rated current (Iu) is 125 A. The conventional thermal current (Ith) is also 125 A, while the rated short-circuit current (Icm) is 2.5 kA. The protection class is IP65, and the permissible operating temperature is in the range of -40°C to +70°C.
